Dif pressure meter
ardiloot/dif-pressure-meter
ESP32 based differential pressure (and air flow) meter. Handheld, battery powered DIY device for measuring small pressure differences (Sensirion SDP810-500Pa).
Boards in 4 GitHub repositories, designed in KiCad, that use the SIL2308-TP by Micro Commercial Components (-55℃~+150℃ 1 N-Channel + 1 P-Channel 11nC@4.5V、12nC@2.5V 125pF 1V 20V 38mΩ@4.5V 4A、5A 800pF SOT-23-6L MOSFETs ROHS). See how each wires it, with its parts, size, README and files; the SIL2308-TP’s symbol, footprint and pinout are on its own page.
